HIGHLIGHT: Commentator Barack Obama finds that Charles Murray, author of the controversial "The Bell Curve," demonstrates not scientific expertise but spurious political motivation in his conclusions about race and IQ.

BARACK OBAMA, Commentator: Charles Murray is inviting American down a dangerous path.

NOAH ADAMS, Host: Civil rights lawyer, Barack Obama.

Mr. OBAMA: The idea that inferior genes account for the problems of the poor in general, and blacks in particular, isn't new, of course. Racial supremacists have been using IQ tests to support their theories since the turn of the century. The arguments against such dubious science aren't new either. Scientists have repeatedly told us that genes don't vary much from one race to another, and psychologists have pointed out the role that language and other cultural barriers can play in depressing minority test scores, and no one disputes that children whose mothers smoke crack when they're pregnant are going to have developmental problems.

Now, it shouldn't take a genius to figure out that with early intervention such problems can be prevented. But Mr. Murray isn't interested in prevention. He's interested in pushing a very particular policy agenda, specifically, the elimination of affirmative action and welfare programs aimed at the poor. With one finger out to the political wind, Mr. Murray has apparently decided that white America is ready for a return to good old-fashioned racism so long as it's artfully packaged and can admit for exceptions like Colin Powell. It's easy to see the basis for Mr. Murray's calculations. After watching their income stagnate or decline over the past decade, the majority of Americans are in an ugly mood and deeply resent any advantages, realor perceived, that minorities may enjoy.

I happen to think Mr. Murray's wrong, not just in his estimation of black people, but in his estimation of the broader American public. But I do think Mr. Murray's right about the growing distance between the races. The violence and despair of the inner city are real. So's the problem of street crime. The longer we allow these problems to fester, the easier it becomes for white America to see all blacks as menacing and for black America to see all whites as racist. To close that gap, we're going to have to do more than denounce Mr. Murray's book. We're going to have to take concrete and deliberate action. For blacks, that means taking greater responsibility for the state of our own communities. Too many of us use white racism as an excuse for self-defeating behavior. Too many of our young people think education is a white thing and that the values of hard work and discipline andself-respect are somehow outdated.

That being said, it's time for all of us, and now I'm talking about the larger American community, to acknowledge that we've never even come close to providing equal opportunity to the majority of black children. Real opportunity would mean quality prenatal care for all women and well-funded and innovative public schools for all children. Real opportunity would mean a job at a living wage for everyone who was willing to work, jobs that can return some structure and dignity to people's lives and give inner-city children something more than a basketball rim to shoot for. In the short run, such ladders of opportunity are going to cost more, not less, than either welfare or affirmative action. But, in the long run, our investment should payoff handsomely. That we fail to make this investment is just plain stupid. It's not the result of an intellectual deficit. It's theresult of a moral deficit.
